2 Claims.

The present invention relates to new and useful improvements in haystackers and loaders, and has for its primary object to provide, in amanner as hereinafter set forth, an apparatus of this character which isadapted to be expeditiously mounted for operation on a conventional farmtractor and driven from the usual power take-off thereof without thenecessity of making material structural alterations in said tractor.

Another very important object of the invention is to provide a stackerand loader of the aforementioned character which is adapted to lift theload and hold said load at any desired elevation while it is beingtransported to the' v apparent from a study of the followingspecification, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout the several views, and wherein:

with the present invention, showing the device mounted on a tractor.

Figure 2 is a top plan view thereof.

Figure 3 is a perspective view of the base structure.

Figure 4 is a perspective view of the head.

Figure 5 is a perspective view of the rockable shaft which tilts orrocks the head.

. Figure 9 is a view in side elevation of the hy- ,draulicbrake-operating means.

Referring now to the drawings in detail, it will which has beenillustrated comprises an elongated base structure of suitable materialwhich is designated generally by reference character I. The basestructure I includes side members 2 and front and rear cross members 3and 4, respectively.

'The base structure I is adapted to be mounted,

longitudinally on a tractor 5. Toward this end, the cross member 3 is inthe form of an' apertured plate which is bolted or otherwise firmlysecured to the front end of the frame 6 of the tractor 5. The sidemembers 2 of the base structure I rest at an intermediate point on therear axle housings I of the tractor 5 and are secured thereon by U-bolts8.

Mounted transversely on the base structure I rearwardly of the tractor 5is a beam which is designated generally by reference character 9. Thebeam 9 includes spaced upper and lower bars ID with spacing blocks l lbetween the end portions thereof, between which bars the side members 2of the base structure I pass. Substantially U-shaped brackets l2 aremounted on the end portions of the upper bar l0.

Arms l3 are pivotally mounted for vertical swinging movement on thebrackets l2 and extend forwardly therefrom adjacent the rear wheels llof the tractor 5. A cross member l5 extends between the forward endportions 'of the arms I3. Brace l6 are provided between the arms l3 andthe cross member l5. A head I! is mounted for rocking adjustment on theforward end portions of the arms I3. The head II includes rake teeth IS,a back frame [9, braces 20, et cetera. The teeth l8 are fixed, at theirrear end portions, on spaced, parallel bars 2| and 22. SubstantiallyU-shaped brackets 23 on the bar 22 are ivotally mounted on the forwardend portions of the arms l3 for vertical swinging movement. I

Mounted on the rear ends of the members 2 is a vertical frame structure24 comprising uprights 25 and inclined braces 26 extending betweensaiduprights and said members 2. A cross bar 21 is mounted transverselyon the I upper end portions of the uprights 25. Pulleys be seen that theembodiment of the invention 28 are mounted on the end portions of thecross bar 21. I

Rockably mounted larly extending arms 2!. Suitable cables or the like 30are trained over the pulleys 28 and connected at one end to the arms 29The cables II are connected at I2 to the upper portion of the back frameI! of the head H. A hand on the braces 26 is a transverse shaft 3| whichterminates in right angulever 33 is fixed on the shaft 3|, said handlever being operable from the drivers seat 34 of the tractor 5. Anysuitable means may be provided for releasably securing the hand lever 33in adjusted position.

- Mounted for vertical swinging movement at an intermediate point on theside members 2 of the base structure I is a yoke 35 which straddles thetractor 5. The yoke 35 has mounted thereon an inverted V 36. Forwardlydiverging chains 3'! connect the V 36 to the forward end portions of thearms |3 for raising and lowering said arms with the head I! thereon.

Journaled longitudinally beneath the rear end portion of the basestructure i is a drum 38. The drum 38 is fixed on a shaft 39. Ahydraulic brake 4D is provided for the drum 38. The shaft 39 is drivenfrom the usual power takeoff of the tractor 5 by means including a shaft4| comprising a plurality of sections with suitable universal jointstherebetween. The transmission 42 is provided between the shaft 39 andthe shaft 4|, said transmission being operable from the seat 34 of thetractor 5.

Pulleys 43 and 44 are mounted, respectively, on the cross bar 21 and theV 36. A cable 45. is anchored at one end to the frame of the pulley 43.The cable 45 extends forwardly around the pulley 44, back over thepulley 43 and is secured at its other end to the drum 38 for windingthereon. A guide pulley 48 is provided for the cable 45 on the frame 24above the drum'38.

The brake 4|] receives fluid from a cylinder 41 see Figure 9). A handlever 48, operable from the driver's seat 34 of the tractor 5, isconnected by means including a rod 49 to the usual piston in the fluidcylinder 41.

It is thought that the operation of the apparatus will be readilyapparent from a consideration of the foregoing. Briefly, to load thedevice, the arms l3 are swung downwardly and the head I! is swung to thefull line position of Figure 1 of the drawings through the medium of thehand lever 33. Of course, the tractor 5 is driven forwardly for scoopingthe hay from the ground onto the head When a load has thus beengathered, the lever 33 is swung forwardly for swinging the head I!upwardly to the dotted line position of Figure 1 of the drawings forretaining the hay on said head. The brake 40 is then released and thetransmission 42 is placed in gear for actuating the drum 38 from thepower takeoff of the tractor 5 in a manner to wind the cable 45 on saiddrum. Thus, the arms l3 with the head I! thereon are swung upwardly toelevated position. When' the desired elevation has been reached, thetransmission is again put in neutral and the brake 40 is applied forsecuring the drum 33 against rotation thereby retaining the load inraised position. The hay may then be transported to any desiredlocation. When the location at which the hay is to be discharged isreached, the lever 33 is swung rearwardly for permitting the head H toswing downwardly, by gravity, thereby dumping the hay.

It is believed that the many advantages of a tractor-mounted hay stackerand loader constr'ucted in accordance with the present invention will bereadily understood, and although a preferred embodiment of the apparatusis as illustrated and described, it is to be understood that changes inthe details of construction and in the combination and arrangement ofparts may be resorted to which will fall within the scope of theinvention as claimed.

What is claimed is:

1. In a hay loader and stacker, a base struc ture comprising ahorizontal rectangular frame having a front cross-member apertured forrigid bolting to the front end of a tractor frame and side members of alength to extend across and rearwardly beyond the rear axle housings ofthe tractor at opposite sides of the latter, means to rigidly bolt saidside members on said rear axle housings, a transverse beamcarried by therear portion of said base structure and projecting laterally beyondopposite sides of the latter, arms pivoted at their rear ends to theends of said beam for vertical swinging movement in planes outwardly ofthe traction wheels of the tractor, said arms extending forwardly beyondthe front of said base structure, a buck rake pivoted for verticaltilting movement on the forward ends of said arms, a vertical framerigid with and rising from the rear end of said base structure, guidescarried by the top of said vertical frame, a transverse rock shaftJournaled above the base structure directly in front of said verticalframe and having crank arms, a cable attached to the back of the rakeand extending rearwardly over said guides and then forwardly andattached to said crank arms, a lever for rocking said rock shaft to tiltthe rake relative to said arms, and power-operated means to verticallyswing said arms to raise the rake.
